Re: E1 balanced versus E1 unbalanced

Balanced interfaces typically use three conductors and three signal states: high, low, and ground. The high and low signals mirror each other. Unbalanced interfaces use only two signals: signal and ground.

Which you choose depends on what your provider offers, i.e. if your provider only offers E1 balanced then you'll need a line card/adapter which supports balanced.

E1 balanced versus E1 unbalanced

Many Cisco E1 devices can be configured through software to be balanced or unbalanced. Traditionally, this was hardware-based...

E1 balanced is on a 4-wire twisted pair cable with RJ48 pinouts

E1 unbalanced is not twisted pair, but coaxial with BNC connectors

Twisted-pair cable is balanced. Coaxial is unbalanced.
